Hi Lars and thank for your quick answer, i had a little look at the kernel
Changelog and i saw they changed sg_set_page, suggestin use of
sg_assign_page.I went to drbd/drbd_worker.c changin sg_set_page to sg_assign_page and it
compiles without problems. So i solved the oops usin the rc2...
BUT, even switching to new kernel my problems remains the same...
I have tested latest drbd/kernel with CORE2/QUAD processors and i'm in deep
troubles, syncer get stuck at 20mb/s with incredible high await/iowait times:
[root at nas1 queue]# iostat -x -m 1

I'm sure it isn't a raid issue because readin&writin directly to the
filesystem i have 300+ mb sustained with very low iowait/await/svctime
values.
Additionaly, changin processor back to old P4 solves the problem... no
iowait, syncin drbd up to 200 mb/sec
Anyone out there usin drbd with dual/quad core processors?
Any help will be very very appreciated...

so long and thank for all the fish
